Paracelsus (/ˌpærəˈsɛlsəs/; born Philippus Aureolus Theophrastus Bombastus von Hohenheim, 11 November or 17 December 1493 – 24 September 1541) was a Swiss German[3] Renaissance physician, botanist, alchemist, astrologer, and general occultist.[4] He founded the discipline of toxicology.[5] He is also known as a revolutionary for insisting upon using observations of nature, rather than looking to ancient texts, in open and radical defiance of medical practice of his day.[5] He is also credited for giving zinc its name, calling it zincum,.[6][7] He introduced terms such as “gas”, “chemistry”, and he also coined the Arabic word “alcohol”.[8] Modern psychology often also credits him for being the first to note that some diseases are rooted in psychological illness.[9]
